[TechnocratiK]

For some reason, everyone on my team complains to me that the term "coolant" is preferred over "lubricant" (but I can't imagine why). Anyway, the coolant we use is ESSO Cutwell (I can't remember which kind - 40 or 45 maybe?), which can be bought in 4-litre bottles and is usually dissolved in water before use, meaning that one purchase should last at least a whole season.
